With all the small electric vehicles slated to come to market I'm sure you will start seeing more and more of these.

Yeah I know, but Im wondering what size of boat would be fit enough for this esc?

This looks similar to the speed controller in my Golf cart!
I run a AC Motor, its a whole lot quicker than the DC version.

Top speed is around 90 kph..
Pretty sure the speed controller saids 800 amp on it from memory.

This ESC is too heavy even for a 42" 10S mono or cat. But that doesn't matter, it is a low rpm ESC - 20,000 rpm max for a 2-pole motor, 10,000 rpm max for a four pole. It would be appropriate for a large (60"+) scale boat or warship, one that requires the owner to add 20-50 lbs of balast to achieve the scale waterline.
